K&N air filter to stock air box

[Graugaard]

Hey there.

Thinking abut getting the kn filter for my 2008 FI ninja (not pod). however I was wondering, if I need to do something else with the bike, when im pluggin the filter into the airbox? or is it just that simple?

i got a full racing Yoshimura carbon exhaust system on.

oh and is pod filter worth it? trying to find information about it, I can't really see if i should mod it that much/if it is worth the trouble..

i'm so envious of people who have oxygen sensors. not having to deal with jetting. the point of EFI is that it monitors the amount of oxygen coming in and modifies how much fuel it sprays based on a map through the RPM range, so there shouldn't be anything you need to do. the pod filters are nice if you dont frequently get poured on with rain. they make tools you can use to change the fuel mapping to get even more power out of it and do fancy things like change your redline rpm

well the pod is cheaper than the drop in one and i do think there's is a advantage ayyy POWER!!! no no i guess more air in more power out

Are those bikes closed loop? I'd always thought they were standard open-loop EFI, meaning that the does NOT change the fuel ratios to adjust for stuff like that, and that changes have to be done with something like a power commander.

thx guys,
Denmark is the shittiest rain country ever, belive me, and that motorcycle is my only transport, so i gotta travel in rain sometime (but will maintenance the bike after these trips).

A little off topic i know but why did kawa go from FI to Carb?

If you want to go to pod filters, remember that you lose a lot of low end grunt when you take out the airbox. I think you're going to need a PowerCommander to change the A/F mix. I havent read anywhere about the FI 250's changing that automatically; plus if they were open loop EFI, DynoJet wouldn't even bother with making a PC for the 250R, since it wouldn't be necessary

He specifically said he's not going to use pods or remove the airbox.

I think you mean closed loop.
Closed loop means o2 sensor feedback -->EFI module --> o2 sensor-->EFI
Open loop means one way (no feedback), so you can stick a Power Commander on the open "end".

yes sir that's correct. my bad i get so distracted sometimes and forget to proofread. the OP did inquire about info on the pods to see if they're worth it. saying that the filter wasn't a pod filter just was to communicate that it was a drop-in K&N filter, not to say that he completely ruled out the pods.


Graugaard, kawasaki went to carbs for the USA because it's cheaper and they wanted to keep the price down since people just see it as a wimpy beginners bike

Oh...I totally missed that.
I love Pod filters because they make it 10 times easier to remove/clean/work on the carbs...oh, wait.....

Europe has stricter emissions control, which is the main reason (some would say ONLY reason) for EFI.

I just installed one of these filters on my bike. I have a 2009 EFI with a Mivv GP slip-on, which I have been using for a half year now without doing anything with the A/F ratio. It was running abit lean, but nothing that desperately needed to get changed. After I also installed the K&N filter though, it definitely needed a remap. So I don't know how much difference it actually makes, will be exciting to see after the remap. But the quality of the filter itself seems WAY better than the stock one, and the fact that it will last the bike's lifetime makes it worth it anyway imo.

Now my bike is in winter storage at the dealership, and they would take care of the 6.000km service, remap, change to iridium plugs, and new coolant. I'd rather have the race mechanic at the dealership do his magic with the original ECU at the cost of some work hours, than getting the expensive PowerCommander. Can't wait to pick the bike up after the winter

wait cn you use powercommander III for a ninja 250 EFI?

There is the PCIII: http://www.power-commander-shop.com/...070_236-411-00

And there is the PCV: http://www.power-commander-shop.com/....070_17-001-01

However, the PCV is(from another site):
More compact, can take alot more input from the bike, greater range of adjustment, and can be expanded with the AutoTune kit.

Of those two, I would definitely go with the PCV, it's not that much more expensive. I know Guinss on this forum has it. Here's his post about it: http://www.ninjette.org/forums/showthread.php?t=49516

A pod filter with that exhaust will let the bike scream at higher rpms, you'll notice a huge difference on the highway. Low end will suffer a little bit but nothing outrageous. Beware though you may need larger injectors, I'm not sure on that because I have carbs but it's something you should look into.

What's pod?

[choneofakind]

this.



the point of a pod filter is to remove the air box, attach this bad boy (and a breather for your crankcase) and then rejet. the effect is more air flow, which gives you a more responsive bike all through the rpm range, and a power band that is more oriented around the top end, as well as more max hp.

plus high flowing intakes sound nasty

FI bikes can't remove the airbox due to having an Inlet Air Temperature Sensor on the box, not unless the sensor, the air switching valve or pod can somehow be modded to work. Because the pods have almost no air volume and pressure differences I'm skeptical it would work.

[choneofakind]

Really?? buzzkill.

Can't they just drill a hole in the rubber part of the R-0990 and seal the temp probe in? That's what greg737 did in his custom FI system.

What exactly is the air switching valve?

Why does it need to know the pressure of the air? Wouldn't the temp of the incoming air and the data from the exhaust probe be sufficient for computing how much fuel was needed?

Good thing I have carbs, because I know nothing about the FI system on these bikes

I image a custom system you could do what you want. I saw greg737's system and it is a work of art, yet it is not a Kawi system. He has total autonomy on his system.

The air switching valve is the same as the kleen air system on the carb bike, except it is monitored. The pressure (vacuum) is to operate the air switching valve.

Hi Guys,

Can i get a POD K&N Filter for my '09 250r Ninja with dual carburators without any issue like the ones with FI system? I rarely drive on rain.. Tks!!

Juliox

[choneofakind]

@JulioXa Yes it works well with the carbs as long as you re-jet. It flows a lot more air

If anything, the stock Kawi injectors are too large. One of the EFI threads has a good discussion about this.

I installed one of these when I put on the EFI kit. You shouldn't have to worry too much about rain as they are covered in oil (that's what makes it red) which should adequately repel the water. It is significantly louder than the stock airbox.

Hi!!

Im kind of new, and my native language is spanish. Can you please explain me whta do you mean with re-jet? Regards.

Thanks guys!! I think I get it now. I believe these are the little like needles inside the carbs that should have bigger holes on them.

So did you end up getting a Power Commander? I'm going to be in your situation.. full yoshi / k&n air filters.. not sure if I'm going to be too lean.

[austinm911]

I got my bike rejetted some months ago, how would getting an air pod be? Or would I have to rejet once again?
The fuel screw was set at 3.5% CO on gas analyzer. The needle is in groove 3 and the stock main jet is used.

[choneofakind]

Yes you'll have to re-jet if you go to pods

Hi Graugaard.. hope u still around with the same bike...

need to ask, mine EFI version too and have a thought to get full system.. some bikers in my country just p&p the full system without using PC (power comander).. im not sure its good for the bike but i guess the bike will not properly tune..
Did you get PC inside your bike?
May i know your top speed (gps reading) after change to full system?
